    Abstract

    The effect of aluminium billets and H13 steels qualities on the mechanical failure of the extrusion dies was investigated. Secondary AA6063 billets were homogenised at 570 and 580°C for 6 h then cooled by water, fan, and air. The step cooling method was also applied by quenching from 570 to 275°C. It was found that the quality of the secondary billet, in terms of hardness and microstructure, would be comparable to the primary ones when homogenised at 570°C for 6 h and then water-quenched. The quality of H13 steels in terms of wear resistance was improved through cyanidation. It was performed in KCN for 2, 2.5, and 3 h with a cyanide layer of 60, 87, and 115 μm, respectively.
